Warner Bros. Animation and DC Entertainment's latest animated film Justice League: War debuts tomorrow, but its release will also mark the beginning of a new shared continuity for the companies' series of direct-to-video superhero movies -- similar to Marvel Studio's Cinematic Universe.
"This will definitely be the first salvo in doing new movies that are in continuity with each other," JL:W producer James Tucker told CBR in a recent interview. "Our next movie's going to be Son of Batman, and that Batman will be the same Batman that you see in Justice League: War. Basically, we'll have two concurrent series of Justice League movies and Batman movies, and they'll be in continuity with each other. So it's kind of worldbuilding."
Regardless of what the live action flicks do, DC animated is doing their thing the proper way.
